The influences on water quality of each river by effluents from environmental facilities located in 14 unit watersheds of North- and South-Han River, and Gyungan-cheon were analyzed. Also, the water quality modeling for study area was carried out to analyze the improvement effect of water quality by the strengthening of T-P effluent standard of environmental facilities. For the calibration and verification of model, water quality data and effluent loading calculated for 2006 were used. Data of low water period were used for calibration, and normal water period for verification. The results of calibration and verification were well matched with the real water quality dataset of revers. Also, the validity of the results were estimated using RI(Reliability Index) method. When the T-P effluent standards for environmental facilities were strengthened, T-P concentrations were predicted to improve from 0.025㎎/ℓ to 0.023㎎/ℓ in the outlet location of North-Han River, from 0.056㎎/ℓ to 0.040㎎/ℓ for South-Han River, and from 0.233㎎/ℓ to 0.146㎎/ℓ for Gyungan-cheon. Also, the T-P concentrations of tributaries including Jojong-cheon, Dal-cheong, Sumgang, Chungmi-cheon, Bokha-cheon, Heuk-cheon, and Wonju-cheon were predicted to improve from 0.063㎎/ℓ to 0.010㎎/ℓ, from 0.091㎎/ℓ to 0.053㎎/ℓ, from 0.199㎎/ℓ to 0.100㎎/ℓ, from 0.168㎎/ℓ to 0.148㎎/ℓ, from 0.186㎎/ℓ to 0.105㎎/ℓ, from 0.019㎎/ℓ to 0.013㎎/ℓ, and from 0.822㎎/ℓ to 0.236㎎/ℓ, respectively.

<P>We present infrared multiple photon dissociation (IRMPD) spectroscopy and quantum chemical calculation results for the protonated permethylated β-cyclodextrin (CD)–water non-covalent complex, the simplest β-CD non-covalent complex, in the gas-phase. The IRMPD spectrum in the region 2700–3750 cm<SUP>−1</SUP> consisted of three strong peaks at 3096, 3315, and 3490 cm<SUP>−1</SUP>. These spectral features in the experimental IRMPD spectrum were compared with a large set of infrared absorption spectra predicted using density functional theory (DFT) calculations for the protonated β-CD–water complex. Complex III (see Fig. 4c), in which the water molecule (at the primary rim) and the proton (at the secondary rim) were separated, was found to suitably reflect the main spectral characteristics found in the experimental IRMPD spectrum. The absence of the homodromic hydrogen bond ring, due to replacement of hydroxyl groups with methoxy groups in permethylated β-CD, rendered the primary rim open compared with the unmodified β-CD ‘one-gate-closed’ lowest energy conformer. This study demonstrates that IRMPD studies combined with DFT theoretical calculations can be a good method for studying molecular interactions of large host–guest pairs.</P> <P>Graphic Abstract</P><P>Water was found to interact with permethylated β-CD through multiple hydrogen bondings with methoxy groups of the rim. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c3cp54841d'> </P>

This reasearch aims to investigate the effects of an internal carbon source in the dentification of piggery wastewater. In this study, the raw wastewater and the effluent from each of anoxic basin and anaerobic basin were used as the internal carbon sources. The experiments were carried out in batch system and the results are as follows; i)Denitrification rastes were the highest in the raw wastewater asnd the lowest in the anaerobic effluent. ii)The piggery wastewater contained about 60 percent of the readily biodegradable organic(RDCOD), which led to a conclusion that the raw wastewater could be used as the internal carbon source for denitrification. For the efficient denitrificatuon, pre-denitrification process was found profitable. iii) In denitrification, alkalinity production rates were in the range of 3.4 to 3.6 mgCaCO?/mg NO?-N. iv) The denitritation of piggery wastewaster came out to be possible, and the rate of organic carbon consumption decreased about 10 percent.

John Dewey 敎育哲學의 批判 : 實用主義(Pragmatism)를 中心으로

林漢永 연세대학교 인문과학연구소 1959 人文科學 Vol.4 No.-

Since Dewey's death in 1952, many criticisms not only by American scholars but also those from Europe have been made. This article is based upon the attempts of H. H. Home, A. V. Judge, T. V. Rusk, Curtis, W. George Gergler and Russell, who have criticized Dewey's progressive philosophy of education. The criticism of main issues: 1.The main areas of criticism are denial of absolute values. 2.Lack of appreciation of factors beyond the scope of human experience. The author tries to resolve the differences between pragmatism and idealism and gets an idea to reconstruct "Neo-Deweyism for Korean-Education," which will be the main theme to be presented by the author later.

While the enhanced biological phosphorus removal(EBPR), in anaerobic/aerobic condition, was known to remove phosphorus by means of metabolism of poly-Pmicroorganisms, the phosphorus removed could be released in the form of ortho-P in the aerobic fixed biofilm reactor. This study was initiated to investigate the cause of ortho-P release in the aerobi c fixed biofilm reactor. The resutls indicated that the phosporus release was caused by autooxidation. The synthesis and release of phosphrous were related to the ORP and the boundary value for the phase change was about 170mV. In the synthesis phase, the phosphorus removal rate per COD removed was 0.023mgP?/mgCOD?. The phosprous contents of the microorganism were 4.3~6.0% on a dry weight basis.

Human clonorchiasis is one of the most common trematode disease and of very important public health problems in Korea. In this study, the enzyme-linked immunosorbent assay (ELISA) was employed in the diagnosis by use of urine samples in human clonorchiasis. ELISA was performed with veronal buffered saline antigen of Clonorchis, peroxidase conjugated antirabbit IgG and orthophenylenediamine as a substrate by micro-method. The results obtained are as follows; 1. The mean O.D. (optical density) values of ELISA in the urine samples of non-infected human cases was 0.037±0.087. If we proposed the O.D. value 0.1 as a differential point of positive reaction, the specificity ELISA in the urine samples was 93% (187 negative reaction out of 201 non-infected human cases). 2. The mear. O.D. valuses in the urine samples of clonorchiasis was 0.580±0.574 and in the serum samples of clonorchiasis was 1.930±0.623. The sensitivity of ELISA was 87.0% in the urine samples (409 positive reaction out of 470 clonorchiasis cases) and was 88.4% in the serum samples. 3. In the distribution of the O.D. values in the urine samples of clonorchhiasis, false positive rates of cross reaction between C. sinensis and P.westermant were 34.7% in the urine samples of clonorchiasis. 4. When the results were compared between the urine and the serum samples of 181 clonorchiasis showed that 88.7% gave same reactions. In the clonorchiasis cases, the O.D. values between the urine and the serum simples were significant at a level of p<0.01. 5. In rabbits, the O.D. values of the urine and the serum samples in 16weeks after infection with C. sinensis metacercariae to were greatly increased than those of the urine samples in preinfection. The O.D. values in the urine samples increased accoording to intensity and course of infection. In conclusion, results of this study suggest that ELISA using the urine samples is more applicable in the diagnosis of human clonorchiasis in mass screening.

The changes of serum and urine IgG levels were observed with the ELISA (enzyme-linked immunosorbent assay) at before and after treatment in human paragonimiasis. Serum and urine samples from 18 cases of confirmed paragonimiasis were tested at before and 12 months after treatment with praziquantel 75mg/kg t i d for 2 days. The ELISA was performed with veronal buffered saline antigen of crude Paragonimus westermani adult worm with the protein concentration of 14.3㎍/ml, peroxidase conjugated anti-human IgG (y-chains) rabbit serum and orthophenylene diamine as a substrate by micromethod. The results obtained were as follows; 1. Before treatment, the mean diameter of wheal size (mm) by the intradermal test was 14.3±3.9, 17 positive reaction out of 18 paragonimiasis cases showed and pseudopodia showed at the wheal by the intradermal test in the 11 out of 18 cases. But 12 months after treatment, the mean diameter was 13.6?4.6, 14 positive reaction out of 18 paragonimiasis which were treated effectively showed and pseudopodia showed in the 7 out of 18 cases. 2. Before treatment, the mean O.D. (optical density) values in the serum samples of 18 paragonimiasis cases was 1.60±0.37 and 18 positive reaction out of 18 paragonimiasis cases showed if we proposed the O.D. value 1.00 as a differential point of positive reaction. But 12 months after treatment, the mean O.D. values in the serum samples was 1.20±0.46 and 13 positive reaction out of 18 paragonimiasis which were treated effectively showed. 3. Before treatment, the mean O.D. values in the urine samples of 18 paragonimiasis cases was 1.22±0.53 and 17 positive reaction out of 18 paragonimiasis which were treated effectively showed if we proposed the O.D. values 0.50 as a differential point of positive reaction. But 12 months after treatment, the mean O.D. values in the urine samples was 0.26±0.24 and 3 positive reaction out of 18 p-aragonimiasis which were treated effectively showed. 4. Before treatment, the relation of the absorbance values between the serum (y-axis) and the urine (x-axis) samples made the regression equation; y-0.571x+0.913, and showed high correlations (r=0.75, n=18, p<0.001). In conclusion, these findings suggested that ELISA using a urine sample is more feasible and seems to be better suited for the evaluation of treatment effect.

Newly developed albenzole(Zentel® is a broad spectrum anthelmintic with high activity against intestinal nematodes as well as trematodes and cestodes infections. The present study was undertaken to observe the morphological changes of Metagonimus pokogcwa; which was obtained from experimentally infected dogs after treatment with Albendazole. For this study 5 dogs were artificially infected with metacercariae isolated from Plecoglossus altivelist and 3 of them were given albendazole 2 doses of 100mg at the day of 4 weeks after infection. The Motagonimus worms were collected from the small intestine of the dogs which : were autopsied at 24hours after treatment. The fine structures of the collected worms were studied by means of scanning transmission electron microscopy. The findings of the observation were compared with those of untreated worms. The results are as follows: 1. It scanning electron microscopy(SEM), the worms obtained from non-treated dogs showed that the whole surface was armed with many scale-like spices, however the worms obtained from the treated dogs showed that many partially necrotized regions on the tegument were scattered elsewhere surface of the worms. 2. In transmission electron microscopy(TEM), numerous mitochondriae and high electron dense granules were distributed in the tegumental syncytium and muscle layers in the control normal worms. However, in the worms obtained from the treated dogs, the degeneration of mitochondriae and disappearance of high electron dense granules were observed in the tegumental syncytium and muscular layers. It was also observed that some tegumental syncytium and circular muscle layers were detached from basement membrane 3. By Sem observation, the bleb-like structures were formed on the surface of the damaged tegument but not on the sensory papillae of the worms obtained from the treated dogs, and the cilium protruded from the dilated sensory papillae. 4. By TEM observation, it was observed that the degeneration of vesicles in the nerve bulb of the sensory papillae in formed vacuoles in its sensory papillae in the worms obtained from the treated dogs.
